Mn5Si3 is an interesting metallic compound that exhibits several antiferromagnetic phases with different collinear and noncollinear arrangements of magnetic moments. Here, anomalous Nernst effect measurements across the magnetic transitions are reported, indicating a symmetry-breaking modification of the magnetic state at low temperatures, in contrast to previous symmetry analysis.
